Update to this thread. I have found the builder who is going to do the gun for me and I have purchased 2 vintage 1947 Model 70 actions. The serial numbers are close and I may end up building one big gun (for large/dangerous game) and one lighter rifle for plains game and the mountains.
Going to do up a thread on the process. I am ordering some custom rifle books and starting to do some research on what I am looking to do. I have ever done this before and its a whole learning process for sure but keeps me day dreaming and gives me something to work on that's creative in my time off work.
I have, however, come to a crossroads wherein I have to decide on Caliber. Obviously there are lots of options.
I am stuck on whether I want a basic classic AMERICAN caliber like the .270 WIN, 30-06 or one that recently entered into my thought process, .300 Weatherby...which is also very classic and Ameican.
I have decided to pause on ordering some of my items while I allow the universe to speak to me on the question of caliber. Of course, being an avid sheep hunter I am enamored with the idea of a Jack O'Connor .270. That being said, I currently run a 26 Nosler Christensen Ridgeline with which I have killed lots of rams, bilies and a mountain Caribou. I have total and utter faith in this gun to be beaten and function with total reliability and accuracy at the most important moments on extended 14-21 day backcountry trips in the harshest conditions in the high mountains. I have carried it in Asia on several trips and North America on 3 (client/guide) sheep hunts. Although it is long (26" barrel and a muzzle brake) for my liking, it "aint broke" so I would be hesitant to replace it. In Asia, above the treeline it is perfect. For horseback hunts in AB/BC or the territories the length isn't ideal, (although I did kill a gorgeous stone ram this past summer with it). I will be carrying it on my upcoming Blue sheep hunt in Nepal this October for sure.
I also want to use what I am now calling my "Sheep Rifle #2" or simply "my wood gun" for future safaris in Africa with my kids. So I am considering a larger caliber. That said, I know enough about guns to understand that I need to decide what I want. And the answer is I don't really know other than a "classic American hunting rifle custom built to my specifications and style".
The .300 Weatherby has such panache and history in the international big game hunting community. Having read many books about the exploits of the great international hunters like Elgin Gates I have also been enamored by it. That said, it would be a big boomer and heavy recoil and a 24" barrel. I was hoping for a lighter weight gun with a 22" barrel and less recoil. But I simply dont know what I want to do and I am waiting for the universe to speak to me LOL.
I only want an American caliber as I am building my gun in the classic American style. So 7x57, etc isnt on my radar.
Anyways, I really appreciate all of the interesting thoughts here so far.
